Search Functions – SEARCH Key
The ESIB offers numerous functions useful for peak/min. peak searching. The search functions can be
used for marker as well as delta marker functions.
The setups applicable to the available search functions are performed in the MARKER-SEARCH menu.
The search functions are always related to the currently active marker. If the SEARCH key is pressed
while the marker entry mode is active, then all search functions are related to the current reference
marker. If the entry mode of a delta marker is active, then the functions will be applied to the
corresponding delta marker. For the case where no marker is active, MARKER 1 will be automatically
enabled (with peak search). The ACTIVE MKR / DELTA softkey allows toggling between the active
marker and the active delta marker.
If the threshold line is turned on, the peak/min. search functions will only evaluate signals which have a
level above/below the selected threshold. In addition, the search range can also be limited (SEARCH
LIM ON/OFF softkey) by the frequency/time lines (FREQUENCY LINE 1/2, TIME LINE 1/2).
For all peak search functions, the first local oscillator is omitted at 0 Hz if it happens to be displayed.
In the time domain display, the summary markers can be activated and set in addition to the search
functions in menu MARKER-SEARCH.
